Xbox One or PlayStation 4? My Decision

I have had lengthy chats with gamer-friends about this. As a pretty serious gamer myself the decision cannot be taken lightly! However I will only be able to choose 1 console to buy this year… so do I upgrade my PS3, or my Xbox 360?

Obviously the Xbox has already been released, and there has been a lot of hype over the voice commands and the central platform for all your TV-connected requirements, however we will start from the ground up.

Looks

Xbox One

I was a fan of the Xbox 360 design. It looks great, albeit a bit chunkier than the PS3. The Xbox One, however, has a complete redesign and in my opinion it looks a bit shitty. The box is bulkier, plain, and lacks imagination. Sure it will look fairly sophisticated under your TV as your primary media centre, but where is the fun in sophistication! I will say, the Xbox logo looks pretty cool lit up, but other than that I am less than impressed by the overall look of the device.

PlayStation 4

Sony have kept the deisgn a secret, only allowing you to see tiny zoomed in flashes of the device during a video currently available on the PlayStation official page. From what I can see, the PS4 and the Xbox One will look pretty similar, both going for the standard black. However from what I can see, Sony have designed a case with a much more “Stealth Bomber” inspired look with sharp angles and beautiful curves. Even the air-ventilation looks cool with what I can only describe (and imagine from the tiny image) as chevron colouring in white. We will have to wait with held breath as they unveil it at E3.

 

Specs

The specs of the systems are pretty similar, but the PS4 has better graphics processing and faster memory:

The PlayStation just about clinches it for me in the hardware specs.

Extra Features

The exstra features can make and break consoles. Obviously we have heard a lot regarding the Xbox One features which basically allows your Xbox to be your central device for gaming, TV, movies, music and pictures. This is a nice selection, but I already have a Pi and media server to provide that for me which automatically downloads what I tell it to, so I don’t need any of that.

Voice recognition on the Xbox sounds pretty cool, but I don’t buy into it. I don’t want to talk to a device to get it working, believe it or not I would rather have a physical means of doing so such as a remote control. So these features mean nothing to me.

The PlayStation still remains elusive as to all of the features as it is not to be released for a little while, but controller features have been unveiled. A cool new coloured bar allows you to see what player you are playing as, and as you move around the room with friends playing in split-screen mode, the order of screens on the board with move to match the position you are playing at in relation with your friends… cool eh? But not ground breaking.

I guess before I make a decision I need to wait until June 10th to find out the full potential of the PS4, but so far, my money is going Sony’s way and I am looking into purchasing a shiny new PS4.

Outlook will not download emails automatically – Exchange

I have seen this happen a number of times and there are a few fixes.

All fixes seem to point to a mail profile issue. User’s mailboxes will show new emails immediately on the Exchange server, however outlook will not update or download them. Try the following fixes:

1. Control Panel > Mail > Profiles > Copy the primary profile and set that as the default

2. Turn off Cached Exchange Mode

3. Create a new mail profile within Control Panel > Mail > Profiles, and set this as default.

Create an easy online music streaming server

To do this you will need a server. For this you can use a workstation and LAMP install. Please see here for LAMP installation instructions.

I recently purchased a server from Waveride. They provided me with the perfect media server for only 6 euro’s a month. Bargain! I chose to purchase a server online because of the fast disks and internet connection. You will find that your streaming capabilities will be much better with a hosted VPS.

Anyhow! Once I had my LAMP server installed, I simply download an application called SubSonic and install. SubSonic scans your media servers for content and publishes the data to a database which is then presented  by a web front end so you can stream it from anywhere with an internet connection. The great thing is this application comes with a phone app for you to be able to stream music and video to your phones and tablets!

So install SubSonic by typing the following into your terminal:

 

sudo apt-get install openjdk-6-jre

sudo wget http://downloads.sourceforge.net/project/subsonic/subsonic/4.8/subsonic-4.8.deb?r=http%3A%2F%2Fwww.subsonic.org%2Fpages%2Fdownload2.jsp%3Ftarget%3Dsubsonic-4.8.deb&ts=1367026022&use_mirror=freefr

sudo dpkg -i subsonic-4.8.deb

 

You can then access the interface via a web browser by pointing to http://localhost:4040 (if you are accessing it from the same computer as it is installed on).

Once you have it installed and you are able to access the web interface, simply add your music folders, and you are away! Don’t forget to check out the phone applications!

SO with the above setup I am able to access my music collection for virtually anywhere (if my phone can get a 3G connection).

A simple reason why SSDs are awesome!

I could bore you with statistics and speeds… however I can give you one simple reason why SSDs are amazing!

I had an SSD a while back, pulled it out of a laptop ready to install somewhere else, but forgot about it instead. Recently I have been having disk issues on my work laptop so I decided to put the SSD in. Obviously I got my Ubuntu CD ready to install on my laptop, boot the laptop up and BOOM! Ubuntu is already installed, not only that but all my applications I had open are still open where I left off! No hibernation… awesome.
